| Abstract Scope |
The challenges associated with designing new alloys are growing, particularly due to the reliance on critical and strategic elements. These challenges are becoming increasingly significant as demand for these elements grows sharply, driven by the global shift towards non-fossil fuel-based energy systems. To address this, there is a need to rethink our design paradigm and adopt methodologies that prioritize recyclability, paving the way for sustainable metallurgy.
This paper presents examples of a novel approach to manufacturing advanced materials, such as high-performance steels, superalloys, and high-entropy alloys, based on the ‘commodity’ method and utilizing advanced powder technology-based processes supported by thermodynamic simulations. This methodology enhances our ability to recycle complex scrap and e-waste concentrates by leveraging all constituent elements in the design process. Central to this approach is the high-entropy concept, which enables each element—regardless of origin—to contribute positively to alloy performance. |
